The CAT.NO.ET-7 is a low
temperature, single channel
flame photometer designed as a
low cost approach for the routine
determination of sodium and
potassium. Additional filters are
included for the measurement of
lithium, barium, and calcium.

Features:
? Push button ignition
? Switchable decimal point
? Electronic flame failure detection
? Filter wheel for fast changing of analytical parameters
? Fine and coarse sensitivity controls
? Operates on propane, butane, natural gas or L.P.G. supplies
? Recorder output
? Economically priced

Element Detection Limits捡出限Working Range测量范围
Na 0.15ppm 0.50 - 10ppm
K 0.20ppm 0.75 - 25ppm
Li 0.25ppm 0.75 - 20ppm
Ca 1.50ppm3.00 - 40ppm
Ba2.50ppm5.00 - 100ppm

ET-7C
The ET-7C is designed specifically for use in clinical applications. The built-in lineariser circuitry enables readings of both
sodium and potassium, at the normal clinical serum concentrations, to be displayed in mmol.
Analytical Ranges: Na 0.04 - 1.1 mM
K 0.02 - 1.4mM
Detection limits and Working ranges for Ca, Li, Ba are the same as the PFP-7.
Common Specifications
Reproducibility: <1% coefficient of variation for 20 consecutive samples using 10ppm Na set to read 50.0
Linearity: Better than 2% when concentration of 3ppm Na and K and 5ppm Li are set to read 100
Specificity: Interference from Na, K, and Li equal in concentration to test element will be less than 0.5%
Recorder Output: Nominal 1.00V for a reading of 100.0
Services: Electrical: 90 - 125V or 190 - 250V @ 50 / 60Hz
Air: Moisture and oil free 6 liter / minute at 1Kg/cm2 (14psi)
Fuel: Propane, butane, natural, gas, or L.P.G.
Range: 0 - 199.9
Size: 420 x 360 x 300mm
Weight: 8Kgs.
